Brief Summary

The aim is to assess whether a self-help book for coping with shift work will reduce complaints in relation to shift work.

Detailed Description

This study is a randomized controlled trial evaluating the effect of a self-help book for shift work related problems compared to the effect of sleep hygiene advice in participants with shift work disorder. 300 participants will be randomized to receive either the book or the sleep hygiene advice. Participants complete questionnaires about sleep, sleepiness and health at baseline and after 6 months after receiving the written material. The main aims are to assess whether the book is more effective to reduce sleep and sleepiness problems in relation to shift work, and to reduce the prevalence of shift work disorder, to increase knowledge about sleep and circadian rhythms, improve health, and reduce turnover intention.
